This message is followed by messages DFHPA1909 and DFHPA1910, indicating SVC number and CICSSVC DFHSIT override are not correct. DFHKE0104: CICS has been supplied with incorrect SVC number. DFHPA1909: Data is invalid for keyword. Respecify keyword and data. DFHPA1910: SIT override is not recognized. Override is ignored. The probable cause of this issue is the CICS... [More]

A customer recently needed to review an earlier transaction they had created and found that the ONDV data had been wrapped-around. The customer saved their history data in a VSAM file and they needed to increase the size of their historical data. This history file reallocation can be can be changed dynamically through the Configuration Tool. From PRODUCT COMPONENT SELECTION MENU, select OMEGAMON II for CICS. The CONFIGURE OMEGAMON II FOR CICS / RTE: xxxx panel is displayed. On the CONFIGURE OMEGAMON II FOR CICS / RTE: xxxx panel, select 5,... [More]

Hello, we posted a PDF document on the TWS WIKI (path Tivoli Workload Scheduler>TWS Distributed>Distributed-driven scheduling on JES) that compares the two solutions available to schedule wokload on JES from TWS distributed . In fact, there are two products that can accomplish this task: Tivoli Workload Scheduler for Applications for z/OS and the Tivoli Workload Scheduler distributed Agent for z/OS. If you have Tivoli Workload Scheduler and a z/OS system where you would like to schedule workload that does not require the use of the... [More]

Hello Community, this entry means to summarize the main TWSz enhancement that more strongly affected Workload Service Assurance, both in terms of performances and in terms of improved functionalities.

simultaneously. The authors do a great job analyzing situations from a system programmer's viewpoint, including how the
systems programmer can use CICS facilities and services to customize the system,... [More]

The support team says the answer can be as simple as you might have migrated an older OMEGAMON release and did not migrate the KOCARACF sample security exit. You will need to carry forward any changes made to your V4.1.0 sample to the V4.2.0 sample. Typically this is just the class name. You then reassemble using the KOCJRACF module and the logon when switching should no longer be needed. Furthermore, if you did any modification to the KOCARACF module, copy your modifications to the new KOCBRACF sample and assemble KOCBRACF using the... [More]
